We explore the actual problem of locomotive traction asynchronous electric drive control system design with accounting processes in the contact point “wheel - rail”. The article describes the new approach to the locomotive traction drive regulator design based on methods of synergetic control theory. Proposed traction regulator provides the desired slippage velocity of wage wheels against rail surface,...
If two or more Permanent Magnet Synchronous Motors (PMSM) can be controlled by one inverter, a train can be driven by less energy than the present Induction Motor (IM) drive system. First, this paper proposes a method for simulating the movement of wheels and a vehicle to develop a control method. Next, a method is presented for controlling two or more PMSMs by one inverter.
In this paper, a slip and slide simulator is proposed to simulate the dynamic behavior of the electric locomotive. The simulator consists of two inverter-controlled AC motors directly coupled with each other. One motor plays a role of traction motor of electric locomotive, other one is to use to simulate various driving characteristics of railway vehicle including adhesive characteristics, running...
